Devices for Talking-Machines, which inven-" tion is fully set forth in the following specification. a i

This invention relates to talking ma- I chines, and more particularly to correction lodcvices employed in machines used for dietation purposes, when the record is to be transcribed, and it isdesired by the dictator to-impart certain information in regard thereto to the transcriber. For example, a

record having a variety of matters thereon,

among. which maybe a telegraml or other rush work, may be delivered by the dictator to a transcriber, or the dictator may desire to have a correction made in matter-,al'ready dictated, as by erasing or changing certain parts, etc.

The object of the present invention isnto provide a convenient, simple and accurate means whereby the. dictator canwindicate to the transcriber just what action he desires taken;-

. With thisend in view, the invention consists in.- a revoluble disk actuated by the sound-box carriage of the machine, and preferably so as to make one complete revolution during the time that the sound-box is. traveling the'l'ength of the record-tablet,

combined with means whereby thedictator may mark the disk at the point .where a Correction is to be made, telegram takenoff,

or other desired matters'attended to; This disk is removed from thedictation machine transcribers machine and, in cooperation 40 with a fixed scale indicates the position in which the transcriberis to-place the sound box for taking off the telegram or other matter.

The device is capable of being applied to any suitable talking machine provided with a traveling sound-box'fand is shown'in the present application. for the sake of illustration, as applied to the form of machine shown in my pending application Serial No.

The inventive idea involved is capableof receiving a variety of mechanical expres- SlOIlS, one of which, for the purpose of illustratmg the invention, 1s shown in the accompanying drawings, but it is to be exv pressly understood that such drawings are for. the purpose of illustration only; and arenot. designed-to define the limits of the invention, reference being had to the appended claims for this purpose. I

In said drawings-Figure l is a front elevationof a talking machine showing my invention applied thereto; Fig. 2 is a horizontal section through the correction device taken on'the line 22 of Fig. 1, looking in the *direction of the arrow, parts being shown in elevation; Fig. 3 shows the parts of the correction device in side elevation,

and the inclosing chamber'in central vertical section; and F1g..4 .is 3,'VeItlC al sect on of Fig. 3 on the'line 4--4.

W Referring to the drawings,.in which like reference numerals indicate like pa, the baseof the talking machine, containing a suitable motor connected by the gearing 2 to the shaft 3, which on its left-hand end is connected with suitable gearing in a gearbox 4 for driving the record 5 and the sound-box carriage 6. The right-handend of the shaft 3 is connected, in a suitable way .(not shown), to a speed-governing device 7, which} may be of any-desired construction. box 6 is propelled along the slide-way 8. by the usual feed-screw inclosed in said. slide- -way, andis prevented from turning around said slide-way by the engagement of the tail 9 of the sound-box with the guide-rod 10, all of which are preferably constructed in a manner fullyset forth in my afore- 'mentioned application. with the record,- and is placed upon the \at its front is closed by' a wall 13, screwthreaded into the chamber 11, as shown in Figs. 2 and 3. A shaft 14 has bearing in the partition 12 and the wall 13, and pro It will be understood that the sound its, 1 is jects outward through the wall. 13 and to the rear of the partition 12, and on the said shaft, there is keyed a drum 15, around which drumthere is passed accord or band 16, with one end thereof secured to the drum and the other end passing outward through an openin 17 (Fig. 3), and connected to the soun -box carriage at 18. A

spring 19 has one end thereof secured to thedrum at 20 (Fig. 2), and the other end thereof secured to the partition 12 at 21. I

On the forward or outwardly projecting end of the shaft 14, thereis mounted a disk 22 provided with means, as two pins 23 and 24, for securing'a paper disk 25 to the disk 22 to compel it to move therewith. Preferably, there is placed between the disk 22 and the paper disk 25 a suitable padding 26 to form a bed for the paper,,which padding 26 is preferably of material, as felt, that will yield sufficiently to permit the paper disk 25 to be punctured, as hereinafter described.

A spring blade or lever 27 is pivotally mounted at 28 at one side of the'disk 22, and

or member 32, here shdwn-as a metal point,

by means of which the operator is enabled to puncture or perforate the paper disk, the felt disk 26 yielding to permit thisaction. But while this particular form of marking point is preferred, any other means of marking the surface of' the paper .disk (as,

for example, a lead point) maybe employed within' the spirit of the invention. The extreme end of the spring blade or lever 27 or the knob 31has thereon a pointer 32,

pointing toward the word Correction,

Rush, Telegram, -etc., when the lever is adjusted in the" desired position.

' On the portibnbf the shaft 14 which projects inward through the partition 12, abell 33 is secured, as by aset-screw 34, so'that the'bell-revolves with the shaft 14. Pivoted to the bell 33is a pawl'35 (Fig. 4), 'normally held against a lug or pin 36 by a spring 37, which spring, hOW GVBI, permits the pawl to yield or move toward the spring,

as hereinafter described. This pawl 35 has a cam face 38, which engages a corresponding cam face 39 of an arm 40 pivoted at 41 to the wall of the chamber 11, the arm 40 turning about its pivot, and having one end ofa spring 42 secured thereto and the other end secured to the .fixed pivot, as clearly illustrated in Fig. 2. If desired, the portion of the chamber 11 to the rear of the bell may be employed for housing other parts of the mechanism, and as here shown inoutline, it is used to house .a'switch 43 for controlling the electric motor which switch is operated through a train of gearing 44 and a shaft 45 having a knurled end 46 projecting to the front; but

as such switchmechanism forms no part of the present invention, it is not illustrated in detail. 4

Theface of the paper disk 25 has thereon a series of concentric circles, here shown as eight, leaving suitable spaces between the circles, and these circles are crossed by ap proximately radial lines, but preferably struckon a slight curve, with the pivotal as here shown, the words Correction,

Rush and Telegram. At ..a certain point, and preferably at the top edge of the front of the wall of the chamber 11, there is a pointer 47 (Fig. 1), and when the sound-box carriage 6 is in its extreme lefthand position, and ready to commence the dictation which is to form the record on the record tablet 5, the zero point of the disk 25 is immediately opposite said pointer 47.

Operation: The machine having been started, the sound-box carriage 6 is propelled from left to right in Fig. 1, and as it does so, it acts to unwind the cord 16 from the drum 15, thereby serving to revolve the drum, and with it the shaft 14 and the paper disk 25, against the tension of the spring 19. The diameter of the drum 15 is such that when the sound-box carriage '6 has reached its extreme right-hand position, the

revolution, and have brought thezero point on thd scale again opposite the pointer 47, and when the carriage is returned to its normal position at ,the extreme left, the spring 19 acts to revolve the drum 15 in the paper disk 25 will have made one complete reverse direction, and again wind the cord or band 16 thereon. Now let'it be assumed that when the carriage has reached the pos1- tion shown in Fig. 1, with the paper disk 25 standing-with the scale figure 10 thereon opposite the pointer 47, the dictator desires to dictate a telegram. He turns the spring blade arm or lever 27 on its pivot until the pointer 32 points to the circle immediately under the Word Telegraml, and depresses the button 31, thereby causing themarking point 32 to mark the disk 25. (as by making a perforation This mark or perforation will be on one of the curved radial lines actually marked on the paper which is opposite the indicating point 47, or. on an imaginary radial line of the same kind which, if extended, would be under the point 47. This necessarily follows, since the mark ing point 32 is on a curved line passing through the center of the disk and the point 47, drawn with the pivotal point of the spring blade 27 as a center. When the record 5 is removed from the dictating machine and passed to the transcriber, the paper disk 25 is also takenoff, and is placed in position on the transcribing machine. The transcriber at once sees that the disk is marked on the circle under the word Telegram, and understands that this is for immediate attention, and therefore advances the sound box carriage 6 until the index 10 opposite the mark on the disk registers with the pointer 47 on her machine, and proceeds at once to take off the telegram. In like manner,.any rush Work which may be at any particular part of the record tablet 5, is taken oil by placing the soundkbox carriage 6 in a position to cause the proper mark on the disk 25 to come opposite the index point 47, when the transcriber proceeds to take off such work. a

The pawl 35 on the bell 33 is so positioned that it contacts with the spring pawl 40 just before the sound-box carriage 6 has reached its extreme righthand position, and thereby acts to raise the pawl 40 against the tension of the spring 42, until the cam face 38 on the pawl 35 has passed the cam face 39 on the pawl 40, when the spring promptly returns the pawl to its normal position, and in doing so causes a striker 4.8 (Fig. 4) to impinge upon and ring the bell, thus indicating to the operator that the limit of dictation of that particular record tablet has been reached. When the sound-box carriage is returned to its normal, position, the spring pawl 35 is enabled to pass the striker pawl 40, by reason of the yielding action of the two spring-pressed pawls, as will be readily understood.

While, for the purpose of particularly describing the invention, the same has been herein set forth in considerable detail, it is v to be understood that the invention is not limited to all such precise details, since equivalents may be substituted therefor, and in some cases parts thereof, as for example, the bell, may be omitted, without varying the spirit or scope of the invention, which is defined in the appended claims.
